The nerve pattern which develops in regenerated limbs (salamander) has been described by VC'eiss and Walker ( '34), Piatt ('39) and Deck ('55). Weiss and Walker amputated one forelimb and one hindlimb in each of 8 metamorphosed individuals of the Plethodontid salamander Eurycea bislineata. Amputation was done near the base of the limb. Regeneration took place in all of the hindlimbs but in only 5 forelimbs. They state that 'Lall 4 limbs were dissected" for a study of the dis-J E A N PIATT PLATE 1 N. FI. br. i . I. M. f. c. r.

There is abundant evidence that the amphibian cord when severed is capable of reestablishing anatomical and functional continuity. Regeneration occurs whether the cord be merely severed or a portion, either homoplastic or heteroplastic in origin, be introduced either in normal or reversed polarity.
